IPA: /ˈbaɪbæk/
KK: /ˈbaɪˌbæk/
The act of purchasing something again that was previously sold or owned, often referring to stocks or shares repurchased by a company.
The company announced a buyback of its shares to increase shareholder value.
Buyback is formed from "buy" (from Old English "bycgan", meaning to purchase) and "back" (meaning to return to a previous state). The term refers to the act of purchasing something back, typically shares or assets that were previously sold.
Think of 'buying' something again, as 'buy' means to purchase and 'back' indicates a return. This helps you remember that a buyback is about repurchasing.
